Question

*Quadrilateral ABCD is an isosceles trapezium AB ll CD. If ∠ D = 72⁰ then find measure of ∠ C ?*

1️⃣ 108⁰
2️⃣ 72⁰
3️⃣ 62⁰
4️⃣ 100⁰​

Answer 1

Answer:

In Quardrilateral ABCD

ANGLE D=72

THEN FIND ANGLE C

Construction:draw line parallel to AD from B towards DC

NOW,ABED is a parallelogram

therefore angle BEC =72(Corresponding angles)

and BE=BC

therfore,angle c is also 72 degree
